Diagnosis
Check atlassian-user.xml for repositories and ordering. The LDAP should come first and the hibernate tag second:
1
2
<hibernate name="Hibernate Repository" key="hibernateRepository" description="Hibernate Repository" />
There should be no osuser tag:
1
2
<osuser key="osuserRepository" name="OSUser Repository"/>
Cause
The OSUser repository, left uncommented at the top of the atlassian-user.xml file, will take precedence over the LDAP and Hibernate repository and cause triplicate users in the user browser.
Solution
Resolution
Remove the OSUser repository line from atlassian-user.xml.
